Not just nuclear, but bacteriological and chemical.

The invention has chemical and biomedical applications, and utility in detecting chemical and biological agents used in warfare.

Therefore the chemical and optical purity of the product obtained is low.

Since World War II, bacteriological and chemical weapons have become an increasing possibility.

In addition to nuclear concerns, chemical and biological weapons are a growing threat.

This was a top-secret chemical and biological weapons programme of the apartheid regime.

This natural mineral water retains qualities of unique purity and bacteriological and chemical top quality.

Other applications include remediation of chemical toxic wastes and chemical and germ warfare weapons.

Dr Wouter Basson was head of the apartheid government's chemical and biological warfare programme.

Three types of filtration has been used, (active carbon, sediment filter and reverse-osmosis) to assure the physical, chemical and bateriological purity of the water.

Three companies specializing in nuclear, chemical, and biological decontamination (Magnetek, IT Group and EG & G Technical Services) followed.

If conditions at your post make this a possibility, you may want to plan and prepare a sealed chemical/biological safe-haven at your residence as follows:

For this purpose, please refer to the following fact sheet E 27 "Methods and means available for water physical, chemical, and bacteriological analysis".

With reverse osmosis, only one process is needed for the physical and chemical purification of water.
